Patent GB-261891-A (GB)
Abstract: 261,891. Russell, H., Oct. 16, 1925. Ovens; oven shelves; doors.-The door b of an oven is hinged on pivots b<1>, b<2> engaging in slots c. d extending from back to front of the oven. When the door is in use, the upper pivot, which is of oval section, engages in an enlargement d<1>, at the front of the top slot, and the lower pivot is retained in a sunk recess c<1> at the front of the bottom slot. When the oven space is required for boiling &c. the door is opened, raised to free the pivot b1 from the recess c, pushed back parallel with the oven side, and finally turned to the position at the back of the oven shown in Fig. 5, the upper and lower pivots engaging respectively an enlargement d<2> and a sunk recess similar to those at the front of the slots. In the oven shown, the side e is pivoted so that it may be folded against the back of the oven, thus leaving the hot plate entirely free, as shown in Fig. 5. At the top of the door frame is provided a rebating- strip g against which the top edge of the door closes, and mounted in brackets m so as to be capable of vertical movement to allow the door to pass it when being moved from one of the positions shown in Figs. 1 and 5 to the other. Whilst being moved outwardly from the position shown in Fig. 5 the door engages a projecting lead i on the strip, which it thus raises; on the reverse movement the door again raises the strip by engaging the curved end portion g<1>. A removable oven shelf (not shown) may hang vertically on a hook on the side e, and when in use is supported by tongues which at one end fit corresponding openings j in one side and at the other end rest upon a rib on the side e.

Abstract: 687,026. Ball-and-ring mills. BABCOCK & WILCOX, Ltd. Oct. 31, 1950 [Nov. 1, 1949], No. 26552/50. Class 59 A pulverizer comprising a rotary grinding ring 18, a circular row of grinding balls 20 rolling on this ring, a non-rotary upper grinding ring 21 supported on the balls, and an annular passage 42 for directing a stream of gaseous fluid upwardly around the outer side of the row of balls in order to sweep the pulverized material away from the latter, has the upper grinding ring so formed that oversize particles are able to return to the grinding zone by downward movement over major portions of the upper outer quadrants of the balls. As shown, the ring 18 is carried by a yoke 17 mounted on a driven shaft 14. An upstanding ledge 40 on the ring 18 is of sufficient height to maintain the desired bed of material in the grinding track. The upper ring 21 is pressed on to the balls by four springs 25 attached between the ring and adjustable bolts 27 mounted in the top plate 29 of the housing 10. The shape and arrangement of the ring 20 is such that it leaves substantially the whole of the upper outer quadrants of the balls uncovered so as to permit the recirculation of over-size particles to the grinding zone. The pulverized material is removed from the grinding zone by a gaseous medium which is forced into a wind box 37 and passes therefrom to the lower edge of the ring 18 through openings which are provided in the housing 10 and have vanes 38 whereby the gas stream is given a swirling motion. The stream then passes upwardly through an outwardly-inclined annular orifice 42 formed by plates 43, 44, 45, 48, Fig. 3, secured to the ring 18 and housing, and the pulverized material flowing over the plate 45 is carried upwardly in suspension to a classifier 60. Blades 66 project inwardly from the housing 10 and slope upwardly in the direction of rotation of the ring 18 for the purpose of deflecting the larger oversize particles back into the grinding zone. Small particles of unpulverizable material drop through the orifice 42 into a trap 51 controlled by a slidable gate 50, and large pieces of such material are discharged through a counterweighted relief gate 68 pivoted in one wall of the orifice. The classifier 60, which is carried on the yoke 17 so as to rotate therewith, has outlets 65 and Z-shaped deflectors 61 for returning over-size particles to the grinding zone. Specifications 523,753 and 646,686 are referred to.

Sept. 24, 1931, No. 26685. Convention date, Oct. 4, 1930. [Class 40 (iv).] A loud-speaker comprises a large diaphragm 10, Fig. 1, driven by a moving coil 21, in which the scalar magnitude of the mechanical motional impedance at the coil with its input circuit normally completed (the input circuit having an impedance equal to the resistance of the coil), is equal to the scalar magnitude of the mechanical impedance of the vibratory parts at some frequency between the lowest frequency at which the device operates and that frequency at which the diaphragm ceases to operate as a piston but breaks up and operates by transmission of waves across its surface. The scalar magnitudes of the mechanical motional impedance at the coil and the mechanical impedance of the vibratory parts are preferably equated at a frequency greater than double the resonant frequency of the vibratory parts, e.g. between 100 and 400 cycles per second. Formulµ are given for determining the quantities involved. The diaphragm 10 is preferably of a plastic material such as cellulose acetate or phenol condensate and is formed as the surface of revolution of a parabola or hyperbola, the ratio of the diameters of its ends being 3 : 1, Fig. 3 (not shown). The diaphragm may also comprise a simple cone or a plurality of frustoconical portions connected by a strip cemented to each section, Fig. 4 (not shown). The diaphragm is flexibly mounted at its periphery by an annulus 14 of silk, limp leather, &c., which is clamped between rings 15, and is attached to the flange 17 of a spider 18 carrying the moving coil 21.

Title: Aircraft flight path control apparatus
IPC: G05D1/06
Filed: 1964-07-02
Abstract: 1,026,295. Automatic control of aircraft. BENDIX CORPORATION. July 2, 1964 [July 5, 1963], No.27387/64. Heading G3R. In a system for automatically steering an aircraft during landing, a signal proportional to deviation from a radio glide slope beam and a rate of descent signal are applied to an integrator the output of which controls the aircraft at low altitudes. In Fig. 1 (not shown) D.C. signals from a radio receiver 1, representing angular displacement from a glide path, are normally applied to an amplifier 4 and an integrator 3 the outputs of which are combined to control the pitch altitude of an aircraft through an automatic pilot so that the aircraft is maintained on the glide-path. When the aircraft descends below a predetermined altitude at which the radio signals begin to suffer from ground reflections, a switch 5 is opened to eliminate the proportional signal and a switch 6 is closed to introduce signals from a rate of change of altitude device 30 to the input integrator 3. The switches may be operated manually, at a predetermined time, or at a predetermined altitude. Transient variations of the signals from device 30 are eliminated by subtracting signals representing changes in acceleration of the aircraft, normal to its longitudinal axis, obtained from an accelerometer 34 through a wash-out circuit 33. A low-pass filter 31 reduces noise and a further wash-out circuit 8 ensures that only changes of the rate of change of altitude are effective to control the aircraft.
